Method and device for providing different services in mobile communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• receiving, from a base station, a first signal;
• receiving, from the base station, first information indicating whether the first signal is affected by interference of a second signal;
• receiving, from the base station, a third signal;
• and
• decoding the third signal based on the first information,
• wherein in case that the first information indicating that the first signal is affected by the interference of the second signal, the third signal is not combined with the first signal, and
• wherein in case that the first information indicating that the first signal is not affected by the interference of the second signal, the third signal is combined with the first signal.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit, to a terminal, a first signal;
• transmit, to the terminal, first information indicating whether the first signal is affected by interference of a second signal;
• and
• transmit, to the terminal, a third signal,
• wherein in case that the first information indicating that the first signal is affected by the interference of the second signal, the third signal is not combined with the first signal, and
• wherein in case that the first information indicating that the first signal is not affected by the interference of the second signal, the third signal is combined with the first signal.
